Answer:
cant tell you the answer but i can tell you the person that messed up isn't that good at math
Step-by-step explanation:
B^2 - 4ac > 0
2x^2 +7x -1 =0
b =7 a=2 c= -1
b^2 - 4ac = 7^2 - 4*2*(-1)
= 49 + 8
= 57
Answer:
x=3/22 ; y=-9/44
Step-by-step explanation:
1/2x+1/3=4
=>1/2x=4-1/3
=>1/2x=(12-1)/3
=>1/2x=11/3
=>22x=3
=>x=3/22....(1)
then,
3x+2y
2y=-3 . (3/22)
y=-9/44
The equation for the slope of a line is:
y2-y1/x2-x1
So:
-4-1/1-2 = -5/-1 =5
The slope of the line is 5.
